Consider the reaction between liquid bromine and fluorine to produce BrF3 gas: Brz (1) + 3 F2 (g) → 2 BrF3 (g) At 298.15 K, AG of BrF3 (g) is -229.41 kJ/mol. a) Develop the direction predictor equation for the reaction: b) A flask contains liquid bromine, F2 gas with a partial pressure of Pr2= 0.0060 bar and BIF3 gas with a partial pressure of PBF3 = 1.996 bar. Which way will this reaction go? c) Describe what is happening here- in other words, explain how the two terms in dG either dx favor or go against spontaneity at this point in the reaction. What does the answer to this question say about how heavily favored reactants or products are in this reaction? d) Make a rough sketch of G vs x. Label the relevant features and indicate where the conditions of this problem are on the graph. e) What is the sign of AS? How do you know? What is the sign of AH? How do you know? f) A flask containing this reaction at equilibrium at 298 K has a partial pressure of BRF3 of 2.50 bar. What is the partial pressure of F2 in this flask? Is this answer consistent with your answers to (c) and (d)? Explain. g) Would the spontaneity of this reaction (under standard conditions) change with temperature? Explain.
